GEN-001 (Live Biotherapeutic Product) and Avelumab Combination Study for Patients With Solid Tumors Who Have Progressed on Anti-PD-(L)1 Therapy
Study Details
Study Description
Brief Summary
This is a phase I/Ib, first-in-human (FIH), open-label, dose escalation and dose expansion study to evaluate the safety and tolerability, biological and clinical activities of GEN-001 in patients with locally advanced or metastatic solid tumors who have progressed on at least two lines of approved therapy for their histological subtypes which includes an anti-PD-1 or anti-PD-L1 based therapy (as mono or combination), when administered as combined with avelumab.

| Experimental: GEN-001 with avelumab Dose Escalation Cohort includes patients with advanced or metastatic solid tumors who have progressed on at least two lines of approved therapy for their histological subtypes which includes an anti-PD-1 or anti-PD-L1 based therapy (as mono or combination) will be enrolled. 3 or 6 patients will be enrolled per escalating or de-escalating dose levels. Dose Expansion Cohort includes patients with advanced or metastatic NSCLC, SCCHN, and UC who have progressed on at least two lines of approved therapy for their histological subtypes which includes an anti-PD-1 or anti-PD-L1 based therapy (as mono or combination)will be enrolled. |
